Add project phases - initiation, active, archived

[vildead]

Project can have different phases. The most important is that if the project finishes, it can be archived/moved to inactive stage.

• Update of all the fields should be disallowed
• The stage should be visible - ribbon? color?
• Search should enable filtering by stage

Questions to solve:

• should custodians be able to read the archived records?
• are there any requirements on confidentiality/access restriction after project ends?
• what if the archive folders/locations move - who will have permission to update these records?
• do the records need to be complete or is there some other restriction which would disallow project to be moved to archival phase?
• shall all accesses be revoked or are they required to be manually revoked in order to be able to archive project?
